  • a light source;

    a camera;

    a memory storing computer-readable instructions; and

    a processor to execute the instructions to perform operations comprising;

    generating light pulses using the light source;

    generating multiple exposure windows for the light pulses for the camera, the multiple exposure windows having a sequence comprising a first exposure window having an opening for a duration of time and each other exposure window of the multiple exposure windows having an opening for the duration of time except for a closing for a subset of the duration of time corresponding to a distance from one of the light source and the camera, wherein none of the closings of the multiple exposure windows overlaps another closing of the multiple exposure windows; and

    determining a difference between an indication of an amount of light captured at the camera during the first exposure window and each other exposure window of the multiple exposure windows.
